hi
just came across 'Encapsulated Bonding Technology' from ACE , by which they claim to 'dramatically increases ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups from separations'.
was wondering how they are achieving this ? and what do they mean by 'Encapsulated bonding technology' ??

I'd suppose this is marketing speech for polymeric bonding .

hi
was just wondering if this is 'polymer coated' silica stationary phase ??

given below is the link to details of this column as provided by manufactures

Hi!

Thank you for your interest in these products...I hope I can help explain a bit further.

The ACE Encapsulated Bonding Technology (EBT™) is an evolution of traditional monofunctional silane bonding. Advanced Chromatography Technologies have developed a unique bonding process using proprietary custom manufactured silanes. This technology dramatically increases the ligand coverage of the silica surface and effectively eliminates the negative effect of unbonded silanol groups. An example of the improved inertness this technology provides is detailed within the following link; http://www.ace-hplc.com/products/product.aspx?id=4217.

In addition to improved inertness, the higher ligand coverage results in improved chromatographic performance and stability.

ACE SuperC18 UHPLC and HPLC columns incorporating Encapsulated Bonding Technology were launched at Pittcon 2013 and extremely well received by analysts. From 1st January 2014, the range of UHPLC and HPLC columns available with this novel bonding technology has been further expanded by the introduction of the ACE UltraCore superficially porous particles, which are available with SuperC18 and SuperPhenylHexyl chemistries in 2.5um and 5um particle sizes.

I apologise we cannot disclose more detailed information but if I can be of further assistance please contact me directly.
